From Jim Marshall
I would like to thank you personally for selecting the
JFX-1 Digital Signal Processor.
As a result of the success of the internationally
acclaimed JMP-1 stereo valve MIDI pre-amp our first
digital product, my design team’s next step was to create
a Digital Signal Processor in the same style to expand the
guitarist’s range of usable sounds even further.
The same team who designed the JMP-1 devoted
many hours of research and development to the creation
of the JFX-1, the first Marshall Digital Signal Processor.
As with all products that bear the Marshall logo, no
matter how technically advanced, you can be sure that
the utmost care and highest possible standards of quality
control have been employed in the manufacture of your
JFX-1.
Though designed to be totally user friendly and
extremely intuitive to operate, I strongly suggest that you
read this manual carefully to fully understand and make
the most of the JFX-1’s many features.
I wish you many happy hours exploring the vast
range of sonic possibilities opened up by the processing
power of your new JFX-1.
Yours Sincerely,
From Jim Marshall
